THE PANIC OR SAFE ROOM !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :
A "panic room" or "safe room" is a room connected to a house or other location that can be secured upon entry. They are typically used in case of a break-in or home invasion, but also can be used for refuge from natural disasters like tornados and hurricanes.
At the Flynn-Fletcher house, the entrance to the panic room is located inside a crate in the basement. A ladder leads down to the panic room. The room itself is sparse and metal-lined. For unknown reason cell phone can be used here, even though it would undoubtedly be out of range. The only decoration appears to be a framed needlepoint canvas that says "The Panic room".
To date, Candace is the only member of the family known to use the panic room. For a while she kept her stuffed bear, Mr. Miggins, in the room, and discussed strategy with him on how to capture one of the robots that had frightened her a few minutes before. ("I, Brobot")
Candace would later return to the panic room after she thought Ferb was an alien. ("The Invasion of the Ferb Snatchers")
